PHTHALMIC FRAME.

Application filed August 11, 1922.

To (LU 1071077@ 'if may cou-(fern,

Be it: known that l. WILLiAM J. lVRluHToX, a. citizen ol the` liuitedStates, residing at Southbridge.in the county of Torce'ster and State ofMassachusetts, have invented certain new and useful lmprovements inOphthalmic Frames, of which the following is a specification.

This invention relates to new and useful improvements in ophthalmicInountings and n.ore lntrticularly to the construction of thel lensreceiving frames. 4 Various ways have been attempted for mounting anon-metallic rim upon a metallic rim in such a manner as to retain thenon-metallic rim imposition and have the same hold its position underatmospheric changes and also under the usual wear and tear onthemounting and to apply this nonmetallio covering in, an inexpensivemanner. lThe main object of my invention is to fit the metallic frame ofan ophthalmic mount-- ing with a non-metallic outer shell which will beneat in its appearance when fixed in position and which will withstandvarious atmospheriil changes and the usual wear and tear upon a mountingof this character.

Another object of my invention is the a-pplicagtion of a` non-metallicriml to the metallic` lens rim of `an ophthalmic mounting and inaddition placing a coatingpof liquid cement `over the edges of thenon-metallic rim so as to ret-ain these edges in `position and preventthem from moving away from the edges of the metallic rim as has beenfound to be the case under various atmospheric changes. r

A still further object Aof the invention is the provision of anophthalmic mounting including a metallic rim and an outer non-`1netallic rim applied to the metallic. rim having its longitudinaledges fitted close to the metalic rim at the outer edge of the lensreceiving groove and then apply a coating of liquid transparent cement,said coating to cover the line of joinder between the non-metallic andmetallic rims and extend over onto the non-metallic part, the centralportion of the cementitious coating extending down into the lensreceiving groove and forming a binder between the two side edges of the'non-metallic rim whereby toretai the'min their proper positions.

Serial No. 581,095.

lith the above and other objects in view the invention consists in thenovel features of construction, the combination and arrangement of partsherein-after more fully set forth, pointed out in the claims and shownin the accompanying drawings, in which Figure I is a front elevation ofan ophthalmic mounting constructed Ain accordance with my invention.

Figure Il is a transverse sectional view taken on the line II-ll ofFigure I.

Figure IH is a detail perspective of a. portion of the stock used toform the non-metallic rim showing the same in its normal condition.

Figure lV is a detail perspective illustrating the flat stock rolled toconform to the exterior of the metal eye wire. l

Figure V is a transverse sectional view showing the non-metallicmaterial in position.

Figure VI is a similar view showing how the edges of non-metallicmaterial 'are -forced inwardly onto the metallic inner rim. i

Figure VII is a transverse sectional view showing the application of theliquid cement, and

Figure VH is a transverse sectional view of the non-metallic shell` themetal rim being removed.

Referring now more particularly to the drawings it will be noted that inFigure I the numeral l indicates the'usual lens receiv- -ingf1'ames,suitably connected by means of the nose bridge 2 and furtherprovided with temple members 3 whereby the mounting may be securelypositioned upon the face oi the wearer.

ln carrying out my invention ll prefer to" utilize the stock in the Hatnormal condition .as illustrated in Figure III, the strips 4 of thestock being cut to the desired length and width and then rolled to asemi-circle as at 5 or rolled to the desired shape according to theshape of the metallic rim upon which the coating is to be applied. Thenon-metallic rim 6 is fitted in position over the peri her of themetallic rim as shown in Figure an' the edges of the same pressedinwardly onto the metallic frame by means of a. roller 7 having groovedrunways 8, the edges of the non-metallic casing fitting into the runways8 and bymoving the roller .7 over the edges ofthe casing while in alheated state the edges thereof will be forced inwardly onto the eyeWire land into their proper po sitions. t

- In Figure VH i have illustrated ythe application of a transparentliquid cement, said cement being placed within the lens receiving:groove of the rims l as shown, the groove being 4filled level with theside edges and then by placing the frame ontol a. mould or the likethecementitious material 9 will be spread lover thc joinder between thenonmetallic and metallic rim and after hardening forms a substantialbinder between the edges of the .trim and as this material is oftransparent lquid zyl or other similar inaterial so that fter the formliars been lplaced Within the rim and adjustedv to the proper size, theplastic cement 7 will be forced outgologie@ What l Claim is 1. Anophthalmic mounting including a metallic roove'c'beye wire, 'anon-metallic covering or said eye wire having its edges terminating atthe outer edges of the groove `and ay transparent cementitious materialforming a coating for the metallic material and connected with the edgesof the nonmetallic covering.-

2. An ophthalmic mounting including a non-metallic covering having itsedges a1'- ranged in spaced relation. and a transparentcementltlousmaterlal forming a jolnder between said edges as and for the purpose setforth. y

'ille process of forming a non-metallic coating for ophthalmic eye Wiresconsisting of .rolling a piece of iiat stock to a substantiallysemi-circular shape7 fitting the Same over Ythe metallic eye wireforcing the edges of the non-metallic covering onto the eye wire andapplying a coating ot transparent rementitious material thereto to forma l indcr between the edges 'of the non-metallic cov erlng to retain thesame in position on the eye wire.

4. An ophthalmic mounting including grooved metallic \vires,n`onmetallic cas' ings fitted over said eye Wires with the edges thereofdisposed upon opposite sides of the groove and a transparentcementitious mate rial 'forminga binder between the edges of thenon-metallic casing to retain the same in position upon the eye Wire.
